We request a quote to fabricate 5 boards.

Please provide quote for various turn-time options.  

Directions for the boards are listed below.  Please contact me with any
questions.

Thanks


1)   Plot PCB-R1.* disk files included, 12 EXTENDED GERBER files total.  
     Drill drawing can be used for reference.  All dimensions are in 
     MILLIMETERS.
 
2)   See attached list of apertures (PCB-R1.APP)  

3)   Board material should be standard FR4.

4)   Use green solder mask, SMOBC.

5)   1/2 oz. copper if acceptable.  

6)   Board size is 121.5 mm X 43.5 mm (4.78 in. X 1.71 in.).

7)   There are separate silkscreen file for the top (PCB-R1.SST) and bottom
     (PCB-R1.SSB) of board.  Silkscreen should be trimmed away from areas where 
     it contacts surface mount pads.  It's OK for silkscreen to cover vias, if 
     that is allowed.

8)   This is an 8-layer board.  The board stackup should be as follows:

	TOP   --------------------  PCB-RI.TOP
	GND   --------------------  PCB-R1.GND
	IN1   --------------------  PCB-R1.IN1
	VCC   --------------------  PCB-R1.VCC
	VDD   --------------------  PCB-R1.VDD
	IN2   --------------------  PCB-R1.IN2
	GND   --------------------  PCB-R1.GND
	BOT   --------------------  PCB-R1.BOT

9)   Notice that the GND layer (PCB-R1.GND) is used twice.
  
10)  Board thickness should be 62 mils.  Layer thickness set by board house as 
     appropriate to ease manufacturability.

11)  There are 20 non-plated drill holes (found in PCB-R1.NPT) with centers at:

             -6.05 mm      0.00 mm
